All generic registries expose metadata output, and refactor endpoints to
allow negotiation to handle those responses. Add support for
PartialObjectMetadata being returned for objects as well.

The wrong json package was used, resulting in patches being unmarshaled
with numbers as float64 rather than int64.
This in turn confused HasConflicts() which expects numeric types to match.
The end result was false positives of meaningful conflicts, such as:
```
there is a meaningful conflict (firstResourceVersion: "8517",
currentResourceVersion: "8519"):
diff1={"metadata":{"resourceVersion":"8519"},"spec":{"replicas":0},"status":{"conditions":null,"fullyLabeledReplicas":null,"replicas":0}}
, diff2={"spec":{"replicas":0}}
```

These lines may contain information that cannot be safely logged to
disk. Only deal with known parameters, also bump to V(2) to be
consistent with other logging.
